The figure above shows the absorption spectrum of the molecule HBr. Following the basic procedures of Section 9.6, find: (a) the energy of the “missing” transition; (b) the effective force constant k; (c) the rotational spacing 2B. Estimate the value of the rotational spacing expected for HBr and compare with the value deduced  from the spectrum. Why are there only single lines and not double lines as in the case of HCl?
